摘　　要：In recent years,organic light-emitting device technology has expanded from organic light-emitting diodes(OLEDs)to organic semiconductor laser diodes(OSLDs)with the progress of sophisticated molecular and device architectural designs.In OLEDs,the development of thermally activated delayed fluorescence molecules has been intensively investigated recently.As a result,the internal quantum efficiency of OLEDs containing relatively simple aromatic compounds without precious metals has reached almost 100%.Furthermore,incorporating a distributed feedback resonator structure into the OLED architecture has yielded OSLDs that exhibit the features of current-pumped lasing.In this short review,the authors describe the recent paradigm shift from OLEDs to OSLDs,mainly fromthe perspective of materials innovation.
